Indefinite insult, often used in horrible rap battles on YouTube and Ebaum's to describe someone who is cartoonish, or has cartoon-like qualities. It is unknown whether or not it will offend the person it is said to. Spelling is debatable.

You have a bull on your shirt... you look like a furt... from a cartoon. A coon, and it ruins like prunes... you live with racoons! Animal boom? You live in Kalamazoo.. you foo!

Furt.
A word shrouded in mystery. Due to its connotation in the terrible yet awesome rap battle between two caucasian males in middle school, its meaning is undetermined. It may or may not be an insult. When the large-toothed male Raindrop rebuts by proclaiming Mike a "furt", a new word was created.
Furt's ability to be an insult is dampened by the fact that a majority of people do not comprehend the word.

Spelling is certainly debatable, but an interview of Raindrop has clarified the matter. The "u" is most definitely right. There isn't an I. nope.

You have a {bowl; bull} on your shirt, you look like a... furt from a cartoon. A coon. And it {runes; ruins} like prunes. Animal boom. Kala.. You live in Kalamazoo, you FOO!

An indefinite insult, directed at a single person. Popularized in the infamous rap battle featured on youtube and embaum's. A furt is apparently some sort of cartoon creature, but there is uncertainty of its existence. Spelling is debatable.

You have a {bowl or bull} on your shirt, you look like a.... furt from a cartoon. A coon. And it runes (ruins?) like prunes. Animal boom. Kala.. You live in Kalamazoo, you FOO!
